This isn't a little rise in battery draining. This is an absolutely ridiculous spike in battery usage. I left my phone overnight, and it dropped from 90% to 37% within the 8 hours I left it sleep.
Is there anything I can do? This is stock JPO updated via Kies. Will changing ROM or Kernal fix this? Because quite frankly, I am sick of this. I can't take my phone out for the day without it dying on me.
As far as I can tell, it's not the sensor bug some people are experiencing, as I'm not seeing any suspicious usage in the battery history.
Any help would be very much appreciated as I'm seriously debating getting rid of the phone. I just can't keep it with this appalling battery life.
Thanks.

Turn off auto rotation and data connection (3G). That should improve your battery life siginificantly. You don't need to check your emails in your dream do you?

Thanks for the reply.
I have auto-rotation off as default. It is really plausible that data connectivity is consuming this much power? I never had this much battery drainage in Eclair, even with auto-rotation on, data connectivity on and with the screen at maximum brightness.
I've downloaded APNdroid and will see if turning of data connectivity will help, though I very much doubt it. I'll update here in the case that it does though.
Do you have a exchange account configured?
It's known to drain your battery at that rate when not set to "Push" (generic Wake Lock problem in Froyo)
Also, if you don't mind spending a few bucks, install System Panel app and let it monitor CPU, that way you'll find out which apps are the top battery users (while asleep, battery drain is fairly equal to cpu usage, so the top cpu-usings apps will be the drainers). I have 75% battery left after 10 hours of light usage with Bluetooth. Auto Rotation and 3G enabled.

The only email I use is Gmail, synched to my phone. I've noticed that a fair-few people are having battery issues with a number of suspected causes. The exchange email setting being one and the sensor issue being another.
Would flashing to a custom ROM fix this issue? Or would it still persist? I really wouldn't mind flashing to a custom ROM if it fixes this absolutely pathetic battery life I have at the moment.
if you have any task killers installed try uninstalling.
I had advanced task killer installed and was experienced battery drain..not as much as you but if it helps it al counts

I don't use any form of task manager besides the stock one, which I use on rare occasions.
I'm really debating just trying to flash with any old ROM to see if that fixes the issue.
Are I using the ext4 lagfix? If so there's your problem there. Also to fix gallery bug you just need to root phone and use root exeplorer to copy fixed gallery.apk into /system/Apps. Putting new modded Tom won't fix it as thy mostly use old default gallery which has sensor bug. Look in search to find gallery3d.apk file

I'm not using any lagfix at all. It's stock JPO updated via Kies. The only modding I've done to it is rooted it.
How would I go about checking whether or not the Gallery is the cause of the battery issues?
Rightyho, so I had a O2U SGS with its original firmware, had a bit of an issue with the leaked Froyo that changed the product code but managed to get it back and used JM1.
So JPO came out, thought id try it out. Result: Awful battery life.
JP5 came out (the O2 UK version). Result: still awful battery life.
Thought id try JPA. Result: still awful battery life.
Done all the battery optimisations, deleted the battery stats etc.
Back on JM1 today, battery is at 89% after a 100% 4 hours ago, witch emails, gmail, facebook, and a few other syncing at 30 to 1hour intervals. This is what battery life should be.
The question is, do i give Froyo another go, or wait till another version of Froyo is released? I do like a lot of the new stuff Froyo has, but i also would like my phone to last more than 12 hours!
Suggestions?
Did you try finding out what was causing the battery drain in those froyo roms? 2-3% drain per hour is very achievable, if I just let my phone idle it would only take maybe 1% an hour. I think something else is causing the problem.
I agree with nwsk ive tried numerous froyos and they have all been good for batery life. Theres a few threads about the gallery app and battery usage.
Im pretty sure its both email and gallery, but dont understand why i am getting the issue when others arent?
Had no issues with batt life on froyo either, If it was me I'd wipe it clean and perform a fresh install, see how the battery is then, assuming you haven't already tried that. If you did then something is sucking the battery, doubt it's email or gallery as mine is syncing constantly and I get about 3% drain per hour, in the evening when I turn syncing off I'm getting about a 1-2% drain per hour. My data network is disabled though, but I have wifi on constantly
Ive done several hard resets again, even done a clean install of JM1 then upgraded straight to JPO and after everything is setup, battery just drains rapidly.
Just because you dont have the issue, doesnt mean it doesnt exist, there are several threads with others reporting the issue;
Battery drains after Froyo update
Battery drain problem/sensor usage
Do you suffer from Gallery Sensor battery drainage?
Froyo emial battery drain issues
Just trying to be helpful, nobody said the issue doesn't exist. Have you tried a custom rom?
Doc custom rom is a good try,
but before hands,
mind share the following info?
1. which email client you use? (Samsung email client? SEA? etc?)
2. which email you try to retrieve (yahoo? msn? outlook exchange? etc?)
3. Do you sync other things like contact, calendar together with the setup?
1. Using default Samsung client for email.
2. Exchange and hotmail account being synced every 30mins.
3. SNS? syncs my facebook once a day, also have a few widgets like facebook and engadget doing a 1 hour sync
These are the settings i have on JM1 then choose in Froyo when i upgrade.

I suspect your Exchange give you the problem.
Froyo Samsung default mail client is a bit picky and it drain the battery at certain condition.
This is the strange issue I encounter when I'm on Froyo Samsung email client, read my update, you may suffer for the same issue.
http://forum.xda-developers.com/showthread.php?t=817842
My advise is
1. Sync only hotmail (btw Samsung Premium Social Hub offer a better integration with Hotmail, do give it a try) , do not setup exchange, let it run for a day, if there is no battery drain issue, it confirms that hotmail doesn't give u that issue
2. after No.1 setup exchange, but sync only contact and email, do not sync calendar, set it as "Push" (unless you have data plan constrain), few forummer posted that Push save better battery.
PS: There are other application like FB client for Android, Twitter, FourSquare for Android has the auto update and sync setup by default, go to respective application setting page and disable it, it helps for battery life.
Oh yes ive come across your thread and tried those options too (was using K-9 mails instead) still had pretty bad battery drain though.
I only use SNS for the pictures on my contacts, otherwise i do use the facebook app.
Thanks for your suggestions though.

Are you using any live wallpapers? I had a galaxy thing on and battery drain was terrible.
Nope, never used lived wallpapers, also have the brightness set to manual and down quite low (which im sure most of you will admit is actually still pretty bright).
Hi all,
After noticing my battery was draining quickly, and then after reading this thread , I installed Android System Info to see what was draining my battery so fast. I notice that whenever I would turn on WiFi, the phone will never go to sleep , regardless of what I set the WiFi sleep policy to. After turning off WiFi, the battery still drains heavily.
The WiFi will shut off after 15mins (if you set it to "When screen turns off" or "never when plugged in"). However it seems to keep the CPU on causing it to drain down the battery.
It would seem that whenever WiFi is enabled, the Android system process creates a partial wakelock that does not go away even if you turn off WiFi, and even when the WiFi shuts off as per the WiFi sleep policy. The only way to resolve this is by powering off or rebooting the phone.
You can verify this in Android System Info by going into Battery-History-Other Usage-Partial Wake usage to see how much time the "Android System" process holding a partial wake.
I even did a factory reset on the device; and it is still happening so it doesn't appear to be any app that caused the issue. As I said, it works fine as long as I don't enable WiFi.
I already know of two users having this issue, but I'm wondering if folks having battery problems are going through this as well. Is anyone else having similar issues after using WiFi? I'm hoping someone will be able to identify what exactly is putting the wakelock on and we'll be able to find a fix for it. Other than not using WiFi at all or rebooting the phone after using Wifi.
Does someone know if there is a utility to drill down and see which process would be causing the wakelock? "Android System" doesn't give me any more details.
Any help would be greatly appreciated.
btw I'm not using any battery savers or task killers.
Update...i have the wifi sleep policy set to "never". Also have the network time sync disabled. I am no longer getting alot of battery drain from the Android System partial wakelock.
However, this means WiFi is on all the time....which burns up the battery as well.
Do you think this is a Samsung bug or Android that won't properly let the device sleep when the WiFi sleep policy is set to anything but Never?
Hoping someone at XDA can figure this one out.
I wonder the same thing...I lose about 20% during the night when the phone is not used for about 7 hrs. Not sure if that's normal or not

Set the WiFi sleep policy to "Never" and reboot the phone. Shut WiFi off if possible overnight. You should notice a big improvement with battery life.
Devs - is there any way to see what is wakelocking the Android System process?
The WiFi sleep policy seems to be broke on the Captivate so hoping someone that really knows these things can help out to identify what is going on.
I've had wifi sleep policy to "never" since I got it. Turning off wifi when going to sleep will slow down battery drain when the phone is not in use all night?

It should. Also setting the network to gsm only will use less battery. We need to find a way to see what process is holding that lock. Any dev experts out there please chime in.

That is anything but normal unless you live where your cell signal is very weak. I see about 1% lose every 60- 90 minutes when idle. 10-12% when browsing or reading xda. Dont do heavy gaming do not sure what you should see there. Weak cell signal will kill battery life as can other factors.
I do have a weak cell signal at my house. I'll have to ck it in idle mode in my office, where I have a good signal to see if that makes a difference
On the other hand I just recently installed beautiful widgets and use it's live wallpaper. Also lookout..I'm thinking that could be a battery hog
I'm experiancing the exact issue in the op.
Android System is holding a partial wake lock of about 30-40%
My battery drains 40% overnight.
Are there any fixes for this?
The problem for me was definitely the stock email app continuously polling my Exchange server, killing the battery and my data plan. I resolved it by removing the Exchange server from the stock mail app, and by using Nitrodesk's excellent Touchdown app for mail instead. Touchdown isn't free but it's very good. And now my battery performance is back where to it was prior to the Gingerbread update.
Thanks, Google, for carefully testing this update before releasing it on the unsuspecting public (NOT). You caused a lot of grief for a lot of people.

I may be wrong, but isn't the default email app from Samsung?
Though, you are correct. I setup my work exchange on it as well and it is definitely a killer. Lately I haven't really been giving a **** and just charge my phone every night. However, I might look into this Touchdown app now.

for the stock email app you can configure the sync schedule so it doesn't continuously poll your exchange server overnight. i have my sync schedule set to push when i normally wake up and an hour after i get off of work. during off peak hours its set to manually update.

how did you set this up??
Is the battery life really that good? I really can't get more than 2 hours of SCREEN time with broken use or 3 hours of concentrated use. The International had a thread about this, but those are GSM and running custom ROMs and kernels.
Post your crazy good (or bad) battery Stats here with setups and sync settings. Stock non Rooted preferred, but maybe someone here can convince me to root my phone again!
I'm having the same problem
I'm currently rooted running d3rp but when I've had it stock I get pretty great battery life. Definitely no complaints. Maybe a hardware issue with some phones?
I get about four hours on screen time. And twelve standby. It's enough to get me through the day, and I'm alright with that.

I'm on derpone. I uninstall everything I don't use (Facebook, Twitter, chrome, ect), turn off auto sync, I'm also on the experimental x kernel, unlocked to 1.5ghz, under volted, and have thermal throttling set to the highest (coolest?) Setting. Oh and I have the battery saver on, everything is enabled aside from the brightness control.
...wow I do a lot of stuff.

HTC took it out of the stock settings, the only way to see is with a battery monitor like better battery stats.
Sent from my HTCONE using xda app-developers app
Is Gsam a good monitor? I have power saver off (I see no real difference in battery life) but the screen uses like a maximum of 10% of my power. The kernel uses like 25%. Apps account for 75% of battery usage.
You've probably already searched some if you're asking, but I wanted to make sure you have seen this thread:
http://forum.xda-developers.com/showthread.php?t=2249497
It includes my tip that turned me from disappointed w/ battery life to impressed. (By setting every social app, blink feed, weather, (but not calendar, gmail, or other google services)) to manual sync... and my phone lives most of its life in below average signal strength areas.
Otherwise, I'm running non-rooted, stock, and no battery tweaking apps, or memory freeing apps, etc.

How do I make sure only my google stuff auto syncs? I could care less about the main facebook app. (I need the messenger though, lol).
If I uncheck everything in the Facebook section of Accts and Sync, will it sync at all? Like, when I run the app?
But if GSam is right, then my main problem is the Android Os and kernel. Together, they eat up about 30% of my battery, sometimes more.

Yeah, that's it, you got it. Settings > Accounts and Sync.
My theory was the phone would never be able to turn itself down to a lower power state since one thing or another would always be keeping the data connection active. Used to barely clear 1 day, and now 2 is no problem.
Apps with sync off just update when you open them. Made sense to me!
Good luck.
I have wifi always on with "data connection" unticked and "Sleep mode" ticked because I seen this from htc's website "Keep in mind though that the Sleep mode option for the data connection in Settings > Power, when enabled, overrides power saver mode." Here are some screen shots my brightness is manually set at 20%.
Hello all,
Today i want to share something about a battery drain that i used to have since 4.3 update. Since i updated my phone phone to 4.3, i was having a irregular drain in my battery. It drained about 1% or 2% per hour with wifi and data off. After much research, i found the killer of my battery. First of all, i searched about a reason for my battery draining even in iddle state. For this, we must read about wakelocks first (READ HERE). Please remember to give him thanks for his awesome thread.
First thing, i reinstalled a 4.3 stock based with full wipe. After all apps were installed, the battery seemed to be ok.
After reading about these wakelocks (i recommend BetterBatteryStats for the following), i found out some interesting ones, like secril_fd_interface (fast dormancy related). For who that doesnt know about Fast dormancy, it is a service that is intended to save your smartphone's battery when it is in a mobile data. But for this service to work, it requires the network provider to have that service running too, if the network doesnt have it, your phone will have various wakelocks trying to have a response from network. In my case, my provider does not have this, so i disabled it with this app (works for our model too).
After that, i configured my two email accounts (hotmail and my work's mail, wich is a mycrosoft exchange account) and left the phone with wifi on while i slept. For my surprise, my phone started to drain battery like crazy, it drained 20% overnight with just wifi on. When i opened BetterBatteryStats, the only wakelocks that caugh my attention was the exchange services (more than 200 wakelocks with sync configured to 1h and syncing just 3 days of mails). After this, i knew that if i remove my email accounts, the problem will be gone, but i need those for work.
I read somewhere that the exchange app does not have the ability to sync some folders on our mail (drafts for example), so i removed everything inside drafts and another unused folders, but no lucky.
My accounts were configured to sync 3 days of mails in an interval of 1 hour, so why in hell was more than 200 wakelocks at 1400Mhz of CPU? So i tested one last thing in email app. For my surprise, my battery problem was gone and 80% of email related wakelocks too.
Here is what i did:
1. Openned email app, go to settings.
2. Go to account settings and tapped on the account
3. Rolled down and tap in more settings
4. Tap on Folder sync settings
5. Tapped over avery folder that appeared and changed the sync schedule to manual and period to sync mail to 1 day
6. Did that on all my accounts, now my problem was gone. The battery life increased not only my phone is iddle, but when i'm using it too.
I hope someone else will be helped with this. Any problems to understand the post, feel free to ask.
But this solution isn't actually a solution?
Your battery drain was related to wrong configuration of mail clients. In age of great power menagers (I won't be making advertising now) that's not a problem at all. And you are talking about basic configuration Sorry dude.
The bug on 4.3 is related to "mdm_hsic_pm0" going crazy randomly and preventing from deepsleep and there is no solution for it atm since we are not sure about source of it.

This was not a wrong configuration made by me. Everyone i know that don't have a samsung phone doesnt have this problem with exhange. The other thing, i have these wakelocks (mdm_hsic_pm0) too but my phone enters in deep sleep normally. If you read the tittle of the thread you will know that i am not solving ALL battery issues, but those who MAY have an exchange services excessive drain like i was having. If you have nothing to add, then please don't say crap.
No offence. I just want to suggest that topic name is not precise imho. Especially when we are encountering here just fast dormancy.
